LookupPrivilegeValue

The LookupPrivilegeValue function retrieves the locally unique identifier (LUID) used on a specified system to locally represent the specified privilege name.

BOOL LookupPrivilegeValue(
  LPCTSTR lpSystemName,  // system name
  LPCTSTR lpName,        // privilege name
  PLUID lpLuid           // locally unique identifier
);

Parameters

lpSystemName

[in] Pointer to a null-terminated string specifying the name of the system on which the privilege name is looked up. If a null string is specified, the function attempts to find the privilege name on the local system.

lpName

[in] Pointer to a null-terminated string that specifies the name of the privilege, as defined in the WINNT.H header file. For example, this parameter could specify the constant SE_SECURITY_NAME, or its corresponding string, "SeSecurityPrivilege".

lpLuid

[out] Pointer to a variable that receives the locally unique identifier by which the privilege is known on the system specified by the lpSystemName parameter.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The LookupPrivilegeValue function supports only the privileges specified in the Defined Privileges section of Winnt.h.
